Well, I've just think of this question while I was listening to 11_moji no dengo. You know, I've listened to this song so many times that I couldnt remember, but every time I do I have the same feeling: It really makes me wanna cry TT__TT since the lyric is so sad but it also shows up the strength within human's heart, and Rikki's voice makes this song even better. this song properly gives me the feeling that every mother is adorable~
Is anyone else has some kind of experience like I do? Please go ahead and tell me, which song is heart_touching to you and reason why...I really want to know^^
Anyway, thanhk you for listening to my opinion. Love you, my friends(^O^)

Wow...I have a lot that touches me XD or may be I'm weak lol
A list from the most touching:
1- Haritsuke no Seijo- Of course, this made me cry the first time I listened to it... aren't only the lyrics nor the story, the music arrangement and Joelle's voice touches me so bad T.T
2- Juuichimoji no message- for the reasons you have said before, it makes me cry
3- Shoujo ningyou - It's a very simple and short song, but the voice saying "haha atashi wo aishite" breaks my heart
4- Igen- I just love it, and Revo sings it very well
5- Shiseru otome sono te ni wa suigetsu- The part when Misia and Elef sing toghether always touches me, they put a lot of feelings, and the song is so nostalgic and show us how destiny can be very cruel T.T
6- Swarz, soshite shoujo wa mori no naka- It's a calm but sorrowful song... I can't say anything more
7- Hoshikuzu no Harnais- I feel a lot of empathy for Etoile, and sometimes I had feel that my dog is my best friend XD Of course, is very sad too the thing of being blind, I can't see well so I understand how is to don't like your eyes T.T
8- Yorokobi to Kanashimi no Vin- I don't feel bad for the character here, but It's Remi voice, it's very touching in this song
9- Belle Isle- The story isn't too sad, but for some reason this song makes me feel nostalgic, the music arrangement is so good that touches me, and of course, Rikki's voice is awesome!

I think It's all for me XD Yeah, I cry easily...

PS: I love your pic, rei_15_10

1)Stardust (because I used to be in a similar situation like 2 or 3 years ago and I really wanted to kill the guy XD)
2)11-moji no message ;A;
3)Fuyu no dengon (dkniuwkcds so f*** SAD)
4)HARITSUKE NO SEIJO T___T (Joelle you have such a beautiful voice and it's impossible for me to avoid crying everytime I listen to this song)
5)Gyoukou no Uta (specially the live version because Revo's voice is so...... ;A;)
6)Thanatos gensou wa owaranai....(mitteiru, mitteiru, mitteiru... this part is so.....deep? D: Idk how to explain the feeling I have when I listen to this part of the song)
7)Kono semai torikago no naka de
8)Shiseru otome sono te ni wa suigetsu (as johana_mh said when Misia and Elef are singing together is such a touching moment T^T)
9)Koibito wo uchiotoshita hi Triumph version (so romantic yet sad D:)
10)Ishidatami no akaki akuma (this one doesn't makes me feel sad but I really love the lyrics *W*)

1) Kimi ga Umarete Kuru Sekai: I've always found this song magnificent, but the fact that they speak about the greatnes of being born and then end the song with "In the end, she could not escape the hands of fate …however, there is no need to pity her Because no one can escape, not you, nor me… All’s well ends well…", the "All's well ends well" seriously breaks my heart.
2) Shiseru otome sono te ni wa suigetsu: Elef's cry of despair when he founds Misia dead in the live version is so sad *me hugs Elef* and when they both sing together is just :'(
3) 11-Moji no Dengon for the lyrics as said above
4) El no Rakuen [side A], when El realise it's not a paradise anymore. The music is so sad and beautiful at the same time and it's really sad to see her accept her fate while her father is holding his hand at her and went such a long way only to find her.
7) Kanojo ga Majo ni Natta Ryuu the end when Therese is burnt on the cross is horrible! Especially when during all the song she sung her love and devotion for her child just to end up like this! It's so sad and even more in the live version!
6) Haritsuke no Seijo for the non revenge and very touching lyrics, and Elisabeth hugging Mär
7) Gyoukou no Uta live because OMG Revo and his shaky voice... And the "Kimi ga ima..." part always makes me cry.
8) Tenshi no Chouzou because I find this story heart breaking especially at the end when the little boy is saying “It’s okay now, daddy.” while Auguste dies... And Jimang plays it so well in the live!

There are so many >.<

1.- Tadoritsuku Uta: I endlessly love this song's lyrics, pace, music, story, everything. It never fails to reach my heart.
2.- El no Shouzou: Even though the lyrics are not especially heart-warming, in my totally subjective opinion this is Aramary's best vocal performance. I always get so many feelings from listening to this song.
3.- El no Rakuen [side:A]: amaterasu explained it perfectly, so there's nothing I can add.
4.- Sacrifice and Kanojo ga Majo ni Natta Riyuu: Because everything about these songs is so unfair and miserable. In the case of Sacrifice, the older sister has to sacrifice (no pun intended) herself in order to help her little sister, only to reach such a tragic end. Her "akuma to wa omaetachi no koto da!!" always makes me shiver. Also, I always find the mother's last words really painful to the older sister too. If I were her and my dying mother's last words were "help your little sister", I'd be extremely sad, and even angry. Not "I love you" or anything, just "help her". That's probably my highlight of the song in terms of feelings. About Majo, well, I think everything's said at this point. Therese only wanted Meru to be a happy child and all that shit happened. Also, MIKI's performance always forces me to remember how to breathe.
5.- Kamigami ga Aishita Rakuen ~Belle Isle~: I've always found this soung really touching. Apart from the effect almost all RIKKI's song have in me, the lyrics have an epic and nostalgic mark that I find particularly emotive.
6.- 11moji no Message: For obvious reasons+RIKKI.
7.- Shiseru Otome, Sono Te wa Suigetsu: Also for obvious reasons. My highlight of this song (apart from Elef's scream ;_; ) is that moment when Elef and Misia are singing together and, referring to the moonlight reflected in the water that Misia always wanted to catch as a child, Elef says "you've finally reached it, didn't you?" (or something very similar). I feel it as the moment when Elef realizes he will never again be with Misia, and that he must let her go, just before they say goodbye to each other. And that's why it always brings tears to my eyes.
8.- Haritsuke no Seijo: Dat hug, omg, it makes me cry even now.
9.- Gyokou no Uta: It also makes me cry even now.

There are more, but I could never list all the reasons why so many SH songs never fail to remind me my heart is not as cold as I tend to think.

I think most of us have nearly the same heart-touching song

1) 11 Moji no Dengon
2) Fuyu no Dengon
3) Kono Semai Torikago no Naka de
4) Haritsuke no Seijo
5) Gyoukou no Uta
6) Shiseru Otome Sono te ni wa Suigetsu-Parthenos

Well, I loves those song too, except a little problem with Pathenos. This aint big deal, just a question in my mind: " after all, what is her prediction used for?" To find out the right way avoid trouble in the future? She knew that she will be sacrified, knew that her brother is coming for her (maybe she can see that after her dead Elef will going crazy and start to take revenge....) but she just accepted it. I really don't know why. Is this meaned that prediction gives eternal answers that we can't do nothing about it? Well then why Scorpius wanna hear it? If Misia said that he would never make success in taking the country, will he stop there? ( if this situation happened, I wonder why Misia didnt tell him as well) Or will he still kill her because saying bad thing like that? ( In this case so prediction means telling things that people wanna hear?)
There're still many ways for Misia to have a chance to meet her brother. Doesnt she love Elef as much as he does? So why giving up like that? " Childhood memories is present from Moira" I hardly takes this poor solace, since she wasted many chances to have a better ending instead.
Anyway, thanks for your answers (^O^) I haven't listened to all the songs you mention ( I started a month ago, and by now all I know is about Moira, Marchen, Elysion and Roman) but I'll try my best to catch up with you guys, ok?
*ps:"johana_mh:PS: I love your pic, rei_15_10": thank you ^^

Sorry for going a little off-topic, but I think that was part of the point of Misia's character.

Remember the line in Didymoi that goes "The one to struggle against destiny[Moira], and the one to accept destiny[her]"? The first is a reference to Elef who fought against Moira, in contrast to Misia who merely accepted her will. In Artemisia, Misia also sings "As if wanting to test us...the heavens keep showering us with troubles... and humans can only accept the will of the gods without question..."

Her predictions were probably used by people as a way of reading what fate has in store for them. No matter what they do, Moira has already laid out a fate for them that they cannot avoid. Knowing the future is a double-edged sword in that way, but at least for some people, knowing what lies ahead of them brings some sort of comfort or helps them to accept what will happen. This is probably Misia's case.

In the case of Scorpius, it isn't too clear whether he wanted her for her predictions or just as a sacrifice to Hydra in hopes of winning his battles. Considering what was shown of Scorpius' character, he probably would not have stopped even in the face of an ominous prediction.

Also, being a priestess of Astra probably limited Misia's movements, and considering how far they were separated from each other, it's probably no joke traveling all over Hellenes to find one person. She loved Elef dearly, but the two of them had starkly different views on Fate -- or at least Elef decided to defy Moira once Misia was taken away from him.

Sorry if this went severely off-topic. I think some of my own views were mixed in there, but I hoped that help answer your questions somehow.

The only song I ever actually cried listening to is Haritsuke no Seijo. I think the whole world probably knows how much I've obsessed over this song, but I really cried and couldn't stop crying when I watched the live.

The other song that has come close was Shiseru Otome Sono Te ni wa Suigetsu. I think when I listen to this just when I'm about to go to sleep the full meaning really hits me and I come close to crying... but I never did xD

Lots. No, really, lots. Almost half in every album. Probably.
Let's see... not in any particular order:

- Rinne no Sunadokei: it's just beautiful. Just the idea of a life ending peacefully, aware of having fully lived and deeply loved, makes me melt. When my time comes, I wish my death will be like that.
- Juuichimoji no message: I don't think any explanation is required, so I'll just... go cry again.
- Shiseru Otome, sono Te ni wa Suigetsu: it's not just "heart-touching". It doesn't just "touch" my heart. It grabs it, squeezes it and breaks it into little pieces. Seriously, I find myself moaning "Misiaaa" and crying every time I listen to it XD Plus, I firmly believe the Minami-Revo duet is the most beautiful duet ever. Ever. I can feel my heart breaking in the very moment in which Elef and Misia sing "Sai ni te ni iretanda ne/yo...".
- El no Rakuen, both side E and A: "nee Papa" always kill me a bit. Dunno why. And side A... I'm just going to quote Amaterasu.
- Kanojo ga Majo ni Natta Ryuu: I love Therese, no need to hide it. I sort of feel close to her, she is such a beautiful character. She passed through all that suffering and pain for something she didn't do, and until her very last moment she sings her love and hopes for her beloved son. The curse she casts on the world that burns her at the stake, before dying... gives me shivers every time. What she is saying is "If you really believe I'm a witch, then I'll act like one, and curse you who put an innocent to death". *shivers* Plus, I love MIKI <3
- Kono Semai Torikago no Naka de: "Until I met you, I had no idea of what it is like to be inside a small birdcage, neither I knew the color of loneliness or the meaning of love...". Nothing else to say. Except that the Joelle-Revo duet gives me thrills.
- Haritsuke no Seijo: Oh well, what can I say that has not already been said? Just... Mär and Elizabeth's last embrace is somehow heart-warming, but just a second after I can feel my heart cracking.
- Gyoukou no Uta: first time I listened to it I seriously forgot how to breath. And I only realized it when my lungs started hurting. Mär singing what he has left to the breaking dawn is so moving. Not to mention "Mutti... Hikari... Attakai ne..."
- Ishidatami no akaki akuma: maybe this is the least heart-toughing in the list. But the way Shaytan talks about Layla is somehow sweet, so yeah XD
- Tenshi no Chouzou: I don't feel like I can talk about it without crying. But Jimang's performance is something divine. Just this.

Probably I overlooked some songs, if I can think of some others I'll add them...

EDIT:
Having finally fully listened to all Roman song... I can add a few songs to my list. <3

- Fuyu no Dengon: holy crap I love this song. I cried so hard when I saw it in the live. I couldn't help but laughing a little for Heika's French, but heck, that song destroyed me.
- Utsukushiki Mono: I'll just say that today I was listening to it while walking home, and I started crying in the middle of the street. No joke. Maybe that's because I have alittle sister, and if something was to happen to her I would just... die. When I got home I had the urge to remind her I love her. (but I didn't, dang).
- Hoshikuzu no Harnais: simple. I have a dog. And she's like a little sister to me. So I can perfectly understand Etoile's feelings, though we do not have the same special connection. But she's been with me since I was eight years old, she's an important part of my life. I don't know what I would do if I were to lose her.
- Honoo: I always burst out crying at "Hitori de sabishikunai you ni, futagono la poupee wo katawara ni...", and don't stop until the very end.
